INSULATED RECEPTACLE.

Specification of Letters Patent. i

Patented AuO. 21, 1917.

To all whom t may concern.'

Be it known that I, ANDREW J. Mo-

' ARTHUR, a citizen of the United States, re-

quent re-icing is necessary.

The obj ect of my invention is to provide such receptacles with adequate insulation and also to provide means of insulation which will permit the return 'of the insulating material to the shipper in knockdown form, so that it may be capable of repeated use.

To that end, I take an ordinary barrel and provide it with a sectional insulating lining, consisting of water-proofed boards composed of fibrous material, such as flax, jute, cereal straw, or a mixture of fibers. Because of its strength and fiexibility, such lining can be inserted in and removed from a barrel without mechanical attachment thereto, -and when in place it furnishes a high degree of protection to the contents, particularly as against deterioration due to heat and also against bruising.

In the accompanying drawings, Figure 1 is a central vertical section of a barrel pro- -vided with my removable insulation; Fig. 2 is a central horizontal section of the same; Fig. 3 is a perspective view of one of the staves used in the insulation; and Fig. 4 is a perspective view of one of the insulating heads.

Referring to the drawings, my invention consists essentially of a barrel 10 of ordinary construction, a series of staves 11 composed of flexible `insulating material and a pair of heads l2 of similar material.

Into the barrel 10, with its upper head removed, one of the insulating heads 12 is dropped to form a snugly fitting base 12a. The insulating staves l1 (of which there are enough to completely line the barrel) are placed upright upon this base and bent to conform to the periphery of the barrel staves. All of these staves, except the last of the series, may be arranged loosely in the position indicated and the final one of the series may then be pressed into place between two of the staves thus placed. Because of the resiliency of the fiber, this final stave forms a wedge to hold all of the staves firmly in position. This pressing of the final stave into position may be accomplished with ordinary tools, but I have found that the staves may be more readily and eiliciently assembled with the aid of a composite wedge, especially adapted to the purpose, which I have made the subject of a companion application for patent filed December 3, 1915, Serial No. 64,924. After the staves are in place, the insulated barrel is packed with the fish or other commodity and broken ice; after which the head 12b is laid horizontally upon the upper edges of the insulating sta-ves 11 but not attached thereto and the barrel is headed in the usual way.

I have found that the finer qualities of fish may be successfully shipped in this receptacle for long distances without re-icing, and when unpacked it is practicable, at small cost, to return the insulating material to the shipper in knockdown form.

Having described my invention, what I claim as new and desire to protect by Letters Patent, is:

l. An insulating shipping receptacle comprising a wooden barrel with a removable lining of resilient self-sustaining fiber board, said lining consisting of an unattached base freely resting on the bottom of said barrel, a series of relatively thick staves freely supported by said base, and a head freely resting upon the upper ends of said staves.

2. An insulated receptacle consisting of unattached outer and inner shells, the former being a barrel of ordinary construction and said inner shell being composed of resilient fiber board, formed into disklike heads, and a plurality of interposed staves rigidly held in place within the periphery of the barrel by their own resiliency,

Whereof, I have hereunto subscribed my name to this specification.
